Joesdhk Posted December 12, 2012 Share Posted December 12, 2012 Alright guys just basically wondering if anyone else on the site has an Optimus?! Just want to see what batteries and upgrades people would recommend for it... Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted December 12, 2012 Share Posted December 12, 2012 (edited) Its basically an XTM XT2e looking at it, id upgrade the shocks, set of hyper 7 bigbores would do the trick, if its anything like my 2e, its a pretty solid buggy so little to go wrong, just stock up on the main bits like front lower and top arms, gearbox housings etc.its a Ripmax so many hobao hyper 7 parts should fit. Id recommend upgrading the steering knuckles to CNC ones but they are about Edited December 12, 2012 by NuttyProfessor Quote Link to comment Share on other sites More sharing options...
Joesdhk Posted December 12, 2012 Author Share Posted December 12, 2012 It seems pretty solid to be honest from what ive seen of them and what ive done to mine!! I got it second hand so have a lot of spares to be going on with i have the standard 3 cell battery and also a hardcase 2 cell with it (its very slow with the 2 cell) im thinking i want to see what it can do on 4 cell so what would you recommend?! My ESC says 2s-4s on the side so i assume this means i can run 4s :/ Thanks for your help mate Quote Link to comment Share on other sites More sharing options...

Joesdhk Posted December 12, 2012 Author Share Posted December 12, 2012 So i can run either 2 2cell batteries or one 4cell one i gather? Haha cheers dude Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted December 13, 2012 Share Posted December 13, 2012 (edited) Can even run a 3s im thinking its the 120a esc and a 2370kv motor. One of the first things i did was change the motor and esc so i can run upto 6s, rarely run 6s because it turns my 2e into a ballistic missile i had a hobbyking 150a esc and a leopard 2650kv motor sitting in my old wreaked buggy so thought sod it Edited December 13, 2012 by NuttyProfessor Quote Link to comment Share on other sites More sharing options...
Optimusuk Posted January 9, 2013 Share Posted January 9, 2013 Hello there, I have a DHK Optimus 1:8 buggy. I have since upgraded the motor to a Flux scream 1960kv and the ESC to a Flux Rage 80amp. I have also upgraded the battery to a Turnigy 5000mah 14.8v 4 cell lipo and the thing goes like a bullet now ! Oh yeah, I have also changed the 15 tooth pinion gear to a 21tooth. You have to be extra careful with a 4 cell in this thing as its very fast. I would estimate the speed as a minimum of 50mph. Hope this helps!

RCTFB Posted January 31, 2013 Share Posted January 31, 2013 Yeah I have the DHK. Really happy with them. Hope to do a few videos soon to show it off. Quote Link to comment Share on other sites More sharing options...
Joesdhk Posted January 31, 2013 Author Share Posted January 31, 2013 Do you have any videos of the dhk on a 4s? I was actually selling my car its on ebay now but may keep it if it goes well on a 4s Quote Link to comment Share on other sites More sharing options...
RCTFB Posted March 5, 2013 Share Posted March 5, 2013 Dont have a video just yet. The weather is starting to become good for it. So ill get one done soon.

Rafalle Posted September 21, 2013 Share Posted September 21, 2013 Since 17 September 2013 I own the 8383 DHK model. It is very well build. After 3 hours drive no damage at all. I wish to know witch parts are the most likely to be changed. I suppose the bearings first. I wish to exchange information about this model. Parts seems to be very expensive.

Luke B Posted September 22, 2013 Share Posted September 22, 2013 (edited) Hi there, I have a DHK Optimus, my first and only 1/8th model, and I have to say I think it's brilliant! I'm still running the standard 3S battery, ESC, and motor. All I've done to it is upgrade the steering servo after the original one died and put a heavier weight oil in the shocks to stop the chassis hitting the ground during heavy landings. Oh and the truggy wheels Edited September 22, 2013 by Luke B Quote Link to comment Share on other sites More sharing options...

NuttyProfessor Posted September 22, 2013 Share Posted September 22, 2013 I love my XT2E, running a leopard 2650kv motor with a 6s esc, 56mph on 4s crazy fast setup but takes it with ease, fitted a set of the front CVD'S on the rear to eliminate the weak rear dogbone cups and its been reliable. Goes through tyres at silly rates but its bound to pukka as a stadium truck Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted September 22, 2013 Share Posted September 22, 2013 Thing is, too many people are brand loyal, I like to try offkey stuff to see if its cheap for a reason but i can hardly fault the xt2e in its build quality and standard of drive, now ive tuned the handling to my taste, its a fantastic chassis.

Rafalle Posted September 25, 2013 Share Posted September 25, 2013 I am new in the bussiness of RTR. The 60A ESC it is able to handle only 11,1 V batterries LiPo labeled as 3s, I suppose. A 4S battery will burn the ECS 60A. Quote Link to comment Share on other sites More sharing options...

A 4S battery will burn the ECS 60A. In the manual it says it can take up to a 4S. I've never tried it though. Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted September 26, 2013 Share Posted September 26, 2013 I wouldn't, not on a 60a esc. The xtm xt2e is 4s, 120a esc. Quote Link to comment Share on other sites More sharing options...
Rafalle Posted September 26, 2013 Share Posted September 26, 2013 (edited) THE ORIGINAL CHARGER SUPPORT ONLY 2S 3S. 14.8 Volt may distroy the ECS 60A. We have to check very carefully if the ECS is able to support 4s - 6S Edited September 26, 2013 by Rafalle Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted September 26, 2013 Share Posted September 26, 2013 60a wont take above 3s for certain. And its an ESC, not an ECS by the way. I had to upgrade my ESC on my XTM to a 150a so I could run 6s. Im also thinking that the optimus motor might be a smaller can, the xt2e runs a 3674 sized motor.
